IMPROVEMENT IN MOTORS FOR OPERATING PUMPS.

Specification forming part of Letters Patent No. 203,280, dated May 7,1878; application filed April 15, 1878.

To all whom it may concern:

Be it known that I, J oruv W. LAW, of Bloomington, in the county ofMcLean, and in the State of Illinois, have invented certain new anduseful Improvements in Motors for Operating Pumps 3 and do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawing, and to theletters of reference marked thereon, making a part of thisspecification, and in which I Figure 1 is a side elevation; Fig. 2, asection view.

This invention relates to improvements in mechanism for automaticallyoperatin g pumps through the medium of spring machinery or weight power;and the invention consists in the combination and arrangements of partswhereby the pump mechanism will be automatically and steadily operated,all as will be hereinafter fully described, and pointed out in theclaims.

In the drawing, A represents a frame for supporting the clock-work andoperating mechanism, through the base of which passes the tubularpump-piston B, provided with the usual discharge-nozzleb. Rigidlyconnected to the upper portion of the pump-piston is a collar, 0, whichis connected to the lower .front end of lever D by means of the link E,the lower rear end of said leverDbeing connected to the plate G, securedto the base of the frame by means of the arms F F, pivoted to said plateG.

By means of the above-described mechanism the tubular piston is adapted,through the medium of leverD and intermediate mechanism, to receivepositive vertical or perpendicular reciprocating movement.

To the upper end of the pivoted lever D one end of a pitman-rod, H, ispivoted, its opposite end being connected to the fly-wheel I, or theshaft J, upon which the fly-wheel is mounted, by means of a crank, K.

The connection between the pitman-rod and crank is made by means of thepivoted strap h and the pin h of the crank, said pin resting on line a:m, Fig. 1. Fig. 3 is a detail in a concavity, on the end of the pitmanofclock or train of gearing, in the usual manner, said clock-work or trainof gearing being operated by spring or weight power, as may be deemedmost expedient.

It will be readily perceived that when the clock mechanism is wound upthe pump mechanism will be automatically and steadily or uniformlyoperated, through the medium of shaft J, fly-wheel, crank, andpitman-rod. I am aware that spring or weight machinery or clock-work forautomatically operating pumps is old, and such I do not claim, broadly,as my invention; but,

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination, with the pump-piston B, pivoted lever D, andintermediate connecting mechanism, of the clock-work and intermediateconnecting mechanism, consisting of the pitman-rod H, crank K, fly-wheelI, and shaftJ, the several parts constructed and relatively arranged tooperate substantially as herein shown and described.

2. The combination of the pitman-rod H, provided with the concavity t inone end thereof, and pivoted strap h, and the crank K, provided with theheaded pin 71., whereby said pitman-rod and crank can be easily andreadily connected or disconnected, substantially as herein shown anddescribed.

In testimony that 1 claim the foregoing I have hereunto set my hand this25th day of March, 1878.
